Specification of Letters Patent.

Application filed September 8, 1919. Serial No. 322,332.

To all wlwm it may concern) .Be it known that I, FRANoIs T. JOHNSON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and .useful Improvement in Driers, of which the following is a specification.

My invention relates to driers and applies particularly to those used in connection with the washing of clothes or fabric, although, of course, it might be used in any other connection where it is necessary or desirable to dry articles by artificial heat. One object of my invention is to produce a small, standard portable drier adapted for use in the home.

My invention is illustrated more or less diagrammatically in the accompanying drawings, wherein- F igure 1 is a front elevation with .parts broken away; I

Fig. 2 is a vertical'sectio'n on the line 2'2 of Fig. l.

Like parts are designated by like characters throughout.

. A is the main exterior casing of my drier. It is open at the front throughout the greater portion of its height and is provided with the two laterally swinging doors A A and the vertically swinging door A The doors,

A A are of double thickness and provided with an interior air passage. A A are holes on the outside of the doors A A communicating with the interior air passage A A, A are holes in the inner wall of the doors and communicating also with the interior airpassage A. A, A are perforations across the rear wall which are covered by the slanting hood A which extends entirely across the rear of the drier. A, A are inner walls on the sides and top of my drier: They are open at the bottom and communicate with theinterior of the casing and at the top are provided with the vent A".

1s a gas burnercovered by the protecting box B B is a screen extending entirely across .the interior of the drier and spaced above the burner hood. B is an air mixer in the gas line' C is a rack provided with the rods C C upon which. clothes or other articles tO'bB dried may he supported. This rack is hinged at C and be raised'and held against the back of the di'ier and out of operating position. 1

D is another rack havin%a sheet top-D provided with the rods D It is pivoted at both sides at D on the supporting arms D*, D, which are also pivoted at D on the inner walls of the drier.

E 1s a lip on the inside of the front of the drier at the point of connection of the door A E is a lip extending below the inner wall A? and adapted to engage the front edge of the rack D when it is in the position shown in full lines in Fig. 2. v F are casters or other supports for the drier. G is a stop to limit the movement of D It will be evident that while I have shown 1n my drawings an operative device, still many changes might be made both in size, shape and arrangement of parts without departing materially from the spirit of my inyention and I wish, therefore, that my drawings be regarded as in a sense diagrammatic. The box B is perforated on its bottom as at B and along its-sides, near the top as at B The use and operation of my invention are as follows My drier is designed particularly for use come down to the burnerwhere it will be heated. After it has become heated, it will pass upward through the double walls and out through the vent at the top. I thus establish satisfactory and complete circulation of air bringing the air through the openings near the top down over the articles within the drier and out through the double walls. Thus suflicient air for combustion is furnished and the heated. air containing the moisture passes off.

I have shown a particular form of rack for use in connection with the drier. This is the upper rack as shown in Fig. 2. In-

order to place clothes upon it the doors of the drier are opened and the front edge of the rack is depressed and then pulled forward. As soon as its pivot point has cleared --the'wall of the drier it is in a state of unbalance and the rear end will-tend to fall down, raising the upper end. Thus there is no danger oftherack falling upon or strikposition in the doorway.

ing the user and the rods are brought closer to the front so that the clothes may-be hung upon them more readily. A further advantage is that the rack, having a solid top 7 above the rods, forms a deflector and in a reat measure prevents the escape of heatrom the drier even during the time that the main doors are. open.

In the particular form illustrated the proportions are such as to produce approxi mately 160 F. of temperature. By varying the proportions I can vary the temperature practically indefinitely. If, for example, I increase the length of the hood in the rear of the drier, I increase the temperature. Another way to increase the temperature is to add another burner. This, however, is not so economical and I find that with this burner and proper proportioning of the elements of the drier, I can secure suflicient heat for baking. Such a heat is, of course, not desirable for use in drying clothes, but I mention it as an indication of the possibilities of my invention and although I have shown my invention applied to a drier, I do not wish to be limited to that application.

A. In using the drier, articles to be dried, will usually be hung from the upper rack.

When it is in the position shown in dotted lines, articles will first be hung on the? lower rod, and will belast removed from it; thus the moment an article is hung, it serves to close the door, and to keep the heat from the operators face and to retain it in the drier.

The arrangement of the heater, with th box, is of course to regulate the supply of air to the burner and to protect it irom' any sudden draft, which might put it out.

The gas burner might, of course, be replaced by one or more electric heating elements.

1. A drier comprising a drying chamber with a doorway and a drying rack within said chamber, comprising a plurality of bars and a covering plate above them, said rack adapted to be held in position in the drying chamber and to be moved thence into 2. A drier comprising a drying chamber with a doorway and a drying rack pivotally mounted within such chamber, adapted to be held therein in substantially horizontal position by contact with the ceiling of said chamber, and to be moved thence into position in-the doorway.

3. A drier comprising a drying chamber with a doorway and a drying rack adapted to be held in positionwithin such chamber, 7 and to be moved thence into position in said doorway to partially close it.

4. A drier comprising a drying chamber with a door and a drying rack adapted to be held in position within such chamber and to be moved thence into position in and partly through said doorway to partially close it.

5. A drier comprising a drying chamber with a doorway, and a rack adapted to be held in position in such chamber and to be moved thence into position-in and partly through said doorway, and another rack rotatably mounted within said chamber.

6. A drier comprising a drying chamber with a doorway, and a drying rack adapted to be held in position in such chamber and to be moved thence into position in and partly through said doorway, and another rack rotatably mounted within said chamberand below said first mentioned rack.

7. A drier comprising a drying chamber with a doorway and a'door'therein, adapted, when open to form a shelf on the exterior of said chamber, a drying rack adapted to be held in position in such chamber and to be moved thence into position in said doorway to partially close it and to make said rack more accessible.

8. A portable heat drier comprising a drying chamber having a doorway and means for maintaining a circulation of air through said chamber including double walls and door closures, said means adapted to cause the air to enter said chamber at the top and to leave it at the bottom.

A portable heat drier comprising a drying chamber having a doorway, and means for maintaining a circulation of air through said chamber, including double walls and door closures, said means adapted to cause the air to enter the chamber at "the top and to leave it at the bottom and a rack comprising a plurality of bars with a cover plate across and above them, said rack adapted to be held in position in said drying chamber. and to be moved thence into position in the doorway, and another rack pivotally mounted within said chamber, and below said first mentioned rack.

In testimony whereof, I aflix my signature in the presence of two witnesses this 30th day of August, 1919.
